They will visibly move when you switch from vents to floor etc, if they work properly.

I'll try and find something for you. I've never done this on an F-body before.

The F-body system looks vastly different than what what I had back then. I'll see what I can find... or hopefully a more knowledgeable person can fill you in.

It’s a vaccine line. A small... black brittle vacuum line. I accidentally cracked mine when I was removing my Ecu, found the line and where it was cracked (took forever to locate) and threw some electrical tape on it! Fixed it right up! And haven’t had an issue yet. That was about a year ago. Same symptoms you’re describing. Gotta find that line and follow it.

I also recently removed my ecu. What vacuum line is this? Is this one of the ones that leads to the check valve?

Yes. It is.

I'm going to go through mine again. I'm still having the same problem.

So in my case the issue was the vacuum line that runs from the check valve to the firewall. It had a split in it. So what i did was just throw a new line on there and now it works fine. Thanks to all for the help and i hope this helps others in the future
